Tools Required

  • 5mm hex wrench
  • Torque wrench [paid link]
  • Spoke tension meter
  • Grease (bike-specific)
  • Rim tape
  • Valve stems
  • Tubeless tire sealant
  • Tire levers
  • Rim brake pads (if applicable)
  • 15mm or 17mm open-end wrench (depending on hub type)
  • Hub grease

Installation of the EN355 Hydra Wheelset

Installing the Industry Nine EN355 Hydra wheelset requires precision to achieve the best performance and safety. Follow these steps for a successful installation.

1. Pre-Installation Checks

  • Inspect the wheelset and ensure that both wheels (front and rear) are undamaged and free of any visible defects.
  • Check the hubs for smooth rotation by manually spinning them. If there is noticeable resistance, ensure the internal hub parts are lubricated.

2. Install the Tires

  • For tubeless setups, first, mount the rim tape onto the rims to ensure a tight seal.
  • Insert the valve stems and secure them tightly.
  • Install the tire bead onto the rim, making sure it is seated properly. Use tire levers if necessary but avoid damaging the rim or tire.

3. Adding Tubeless Sealant

  • Once the tires are mounted, add the appropriate amount of tubeless sealant through the valve stems, following the tire manufacturer’s recommendations for the correct volume.
  • Spin the wheel to evenly distribute the sealant inside the tire.

4. Installing the Wheels on the Bike

  • For the front wheel, position it in the fork and secure the quick-release skewer or thru-axle (depending on your bike).
  • For the rear wheel, align it in the frame and tighten the skewer or axle.
  • Use a torque wrench [paid link] to tighten the axle to the manufacturer’s recommended torque settings (usually 12-15Nm for most thru-axles).

5. Brake Installation (if applicable)

  • If you’re using rim brakes, ensure that the brake pads are properly aligned with the rim surface. Adjust the pad spacing to avoid rubbing on the tire.
  • For disc brakes, align the rotors with the calipers and ensure the bolts are torqued correctly (usually 6Nm for rotor bolts).

Adjusting the EN355 Hydra for Optimal Performance

After installation, proper adjustments are necessary for the EN355 Hydra to perform at its best. These include hub maintenance, spoke tension, and tire pressure adjustments.

Hub Maintenance and Adjustments

The EN355 Hydra features the Hydra hub system, known for its high engagement and smoothness. To maintain optimal performance:

  • Periodically check the hub’s engagement mechanism for any signs of wear or damage. The Hydra hub uses a 690-point engagement system, so ensure the internal parts are lubricated and functioning smoothly.
  • If you notice any noise or stiffness, consider servicing the hub by removing it, cleaning it, and regreasing the pawls and ratchet mechanism.

Spoke Tension and Wheel Trueing

Maintaining correct spoke tension is essential for wheel stability:

  • Use a spoke tension meter to measure and adjust the tension of each spoke. Ensure even tension across all spokes for balanced wheel performance.
  • If the wheel becomes untrue (out of round), use a truing stand and 5mm hex wrench to adjust the spoke nipples carefully. True the wheel by tightening or loosening the spokes as needed.

Tire Pressure Adjustments

Correct tire pressure ensures the right balance between grip and efficiency. For the EN355 Hydra, a general guideline is:

  • For enduro riding, maintain tire pressures around 25-30 psi (depending on tire size and rider weight).
  • For downhill, lower pressures of 20-25 psi can provide better traction but make sure not to go too low to avoid pinch flats.

Troubleshooting Common EN355 Hydra Set-Up Issues

During or after installation, you may encounter some issues with your EN355 Hydra wheels. Below are some common problems and their solutions.

1. Noisy Hub

  • Cause: A noisy hub can be due to insufficient lubrication or worn engagement mechanisms.
  • Solution: Open the hub, clean all internal parts, and apply a fresh layer of bike-specific grease to ensure smooth engagement.

2. Tire Leaks (Tubeless Setup)

  • Cause: Improper seating of the tire bead or a leak around the valve stem.
  • Solution: Remove the tire, re-seat the bead, and check for any punctures. If the problem persists, inspect the valve stem for damage and ensure it’s properly installed.

3. Out-of-True Wheel

  • Cause: Spokes may have loosened, or the wheel was not initially trued.
  • Solution: Use a truing stand to identify the issue and adjust spoke tension accordingly. It’s essential to make small adjustments to avoid stressing the rim.

4. Hub Slipping or Resistance

  • Cause: Incorrect hub adjustment or lack of lubrication.
  • Solution: Re-grease the hub and ensure proper installation. If slipping continues, disassemble the hub and check for any worn pawls or springs.

Customization and Optimization for EN355 Hydra

To get the most out of your EN355 Hydra wheels, consider making a few performance adjustments or customizations.

1. Hub Upgrade

Industry Nine offers the Hydra system, which is already a high-performance hub. However, for riders seeking the absolute best, consider upgrading to a custom anodized color option or exploring alternative axle configurations (such as switching to a Boost or Super Boost setup for better frame compatibility).

2. Spoke Lacing Pattern

The EN355 Hydra wheels come standard with a 32-hole spoke configuration, which provides a strong, reliable structure. For riders who prefer more stiffness and less compliance, switching to a 28-hole or 24-hole configuration can reduce weight while maintaining strength. Consult with a professional wheel builder before making any spoke lacing changes.

3. Tire Selection

The EN355 Hydra rims are designed for tubeless setups, allowing for better traction and weight savings. Customizing tire selection based on the type of riding you do can optimize the overall ride quality. Choose a tire with a durable rubber compound for downhill riding or a lighter tire for cross-country racing.

Comparison with Similar Models

When comparing the Industry Nine EN355 Hydra with other high-performance wheels, several factors set it apart.

1. Industry Nine EN355 Hydra vs. DT Swiss EX 1501

  • Engagement: The EN355 Hydra’s 690-point engagement system provides faster engagement compared to the 36-point engagement of the DT Swiss EX 1501.
  • Weight: The EN355 Hydra is slightly heavier due to its aggressive design but offers more durability, making it a better choice for enduro and downhill riders.
  • Price: The EN355 Hydra is priced higher, reflecting its premium build quality and advanced hub system.

2. Industry Nine EN355 Hydra vs. Shimano XTR M9110

  • Hub System: Shimano’s XTR M9110 uses a 36-point engagement system, which is slower than the Hydra system but still offers excellent reliability.
  • Wheel Build: Shimano wheels tend to be lighter, but the EN355 Hydra is better suited for aggressive riding with added strength in the rims.

Understanding Compatibility with Other Drivetrain Components

The EN355 Hydra wheelset is designed to work seamlessly with both 11-speed and 12-speed drivetrains. The Hydra hubs are compatible with both Shimano and SRAM cassettes, provided the correct freehub body is installed.

1. Freehub Compatibility

  • For Shimano cassettes, use the Shimano HG freehub body.
  • For SRAM cassettes, use the SRAM XD freehub body.

2. Axle Compatibility

Ensure that your frame and fork are compatible with the axle type used by the EN355 Hydra. The wheelset supports both thru-axle and quick-release standards, but you need to confirm the specific dimensions for your bike.

By following this guide, you’ll be able to achieve the best possible performance from your Industry Nine EN355 Hydra wheelset, ensuring a smooth, durable, and high-performance ride every time you hit the trail.
